Hi,
I have started the following posts during this project:

What I can see are like theseCold room)
1.I bring down the compressor's run time from 20 hr/day to 18 hr/day
-----> The final product gets affected & Less production.
2.We try to use Water mist system on Condensing coil.
------>No change in KW and suction Pressures.
3.We changed TEX VALVE with higher rating(14TR replaced by 18TR)
------>No changes in Room temp and KW.
4.Duct systems looks very old and sweating.So we changed a portion of duct also, but that obviouly very small portion so we did not expect any saving.
------>No change of Cooling ,KW
The experiement we have not tried is to replaced air-cooled condensing system to water cooled system.But that cost too much and lot of work and I dont have experience about making water chiller.This project when I get started I had zero knowledge about HVAC system.Now get to know bit by bit.
One thing that I get confused:
In Present system I can see Evaporator temperature less than 5 Deg C and Cold room needs below 10 Deg C.So it should be sufficient to cool the room and I can see that the actual the room temperature is bellow 10 deg C.(7-10 deg C).
All I can see that Condensor output temperature is 50 Deg C.Compressor Suction 24 Deg C and Discharge temp is 80 Deg C.
If we change whole air cooled system by new water cooled system then how that will save energy?
Thanks in adavance.
